Abstract

The mold includes a mold tube having pairs of parallel opposed outer surface portions which extend axially of the mold tube. The mold tube defines an axial casting passage having an inlet end for molten metal and an outlet end for a continuously cast strand of the metal. The mold tube is provided with internal concavities which are uniformly distributed peripherally of the casting passage. The internal concavities, which extend in a direction from the inlet end towards the outlet end, become smaller in this direction and are designed so that the strand is shaped as it travels along the casting passage. To form the mold tube, external concavities are impressed or cut in a tubular blank and a mandrel with external protuberances is then pressed into the blank. If necessary, the tubular blank can thereafter be drawn or otherwise processed to produce the desired outer contour of the mold tube.

Dependent claims

Mold for the continuous casting of metal, comprising a tubular member of high thermal conductivity, said member having a longitudinal axis, axially spaced first and second ends, and pairs of opposed outer surface portions extending in axial direction of said member, said member defining an axial casting passage which is open at said ends, and said member being provided with internal concavities which are substantially uniformly distributed peripherally of said passage, said concavities extending in said direction from said first end towards said second end and decreasing in size in said direction such that a continuously cast strand formed in said passage and travelling in said direction undergoes deformation, the opposed outer surface portions of each pair being substantially parallel to one another;

and a tubular jacket surrounding and defining a cooling gap with said member, said jacket having a longitudinal axis and pairs of opposed inner surface portions extending in axial direction of said jacket, the opposed inner surface portions of each pair being substantially parallel to one another.
